UL Standard for Safety Energy Storage Systems and Equipment

active
Organization: UL
Publication Date: 29 March 2019
Status: active
Page Count: 86
scope:

These requirements cover energy storage systems that are intended to receive energy and then to store the energy received in some form so that the energy storage system can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. The types of energy storage covered under this standard include electrochemical, chemical, mechanical and thermal. The energy storage system shall be constructed either as one unitary complete piece of equipment or as matched assemblies, that when connected, form the system.

The systems covered by this standard include those intended to be used in a standalone mode (e.g. islanded) including ″self-supply″ systems to provide electrical energy and those used in parallel with an electric power system or electric utility grid such as ″grid-supply″ systems, or applications that perform ancillary operational modes associated with power generation such as, voltage support and regulation, frequency support and regulation, volt-var, capacity reserve, energy shifting or other utility grid support services.

Energy storage systems are intended for installation and use in accordance with NFPA 70, CSA C22.1, IEEE C2, ICC IFC, ICC IRC, NRC NFC, and NFPA 1.Requirements for installation, with the exception of installation manuals and documents for installation provided with the system are outside the scope of this standard.

This standard covers energy storage systems for stationary indoor and outdoor installations. This standard also covers mobile energy storage systems as defined by this standard. The standard includes requirements for energy storage systems used in residential installations, non-residential installations and wall-mounted applications.

Systems that fall within the scope of UL 1778 and only serve that type of application are outside the scope of this standard.
